The '''World Ocean Database Project''', or '''WOD''', is a project established by the [[World Data CenterIntergovernmental_Oceanographic_Commission|WorldIntergovernmental DataOceanographic Center systemCommission]] (WDCIOC). andThe theproject U.S.leader government'sis Sydney Levitus who is director of the [[NationalInternational OceanographicCouncil Datafor CenterScience]] (NODCICSU) intendedWorld toData preserveCenter and(WDC) disseminatefor [[oceanography|oceanographic]]Oceanography, Silver dataSpring. In recognition of the success byof the [[Intergovernmental_Oceanographic_Commission|Intergovernmental Oceanographic Commission]] (IOC) [[Global Oceanographic Data Archaeological and Rescue Project]] (GODAR project), a proposal was presented at the 16th Session of the Committee on [[International Oceanographic Data and Information Exchange]] (IODE), which was held in [[Lisbon, Portugal]], in October-November 2000, to establish the World Ocean Database Project. This project is intended to stimulate international exchange of modern oceanographic data and encourage the development of regional oceanographic databases as well as the implementation of regional quality control procedures. This new Project was endorsed by the IODE at the conclusion of the Portugal meeting, and the IOC subsequently approved this project in June 2001.

The World Ocean Database represents the world’s largest collection of ocean profile-plankton data available internationally without restriction. Data comes from the: (a) 65Sixty-five National Oceanographic Data Centers and nine Designated National Agencies (DNAs) (in Croatia, Finland, Georgia, Malaysia, Romania, Senegal, Sweden, Tanzania, and Ukraine), (b) International Ocean Observing Projects such as historicalthe completed [[WOCE|World Ocean Circulation Experiment]] (WOCE) and Joint Global Ocean Flux Study (JGOFS), as well as currently active programs such as [[CLIVAR]] and Argo, (c) International Ocean Data Management Projects such as the IOC/IODE Global Oceanographic Data Archaeology and Rescue Project (GODAR), and (d) Real-time Ocean Observing Systems such as the IOC/IODE [[Global_Temperature-Salinity_Profile_Program|Global Temperature-Salinity Profile Project]] (GTSPP). All ocean data acquired by WDC Silver Spring – USA are considered as part of the WDC archive and are freely available as public ___domain data.

==Comparison of World Ocean Databases==

The World Ocean Database was first released in 1994<ref>{{cite web |url=http://www.nodc.noaa.gov/OC5/indpub.html#World%20Ocean%20Atlas%201994 |title=World Ocean Atlas 1994 series |publisher=[[National Oceanographic Data Center]]}}</ref> and updates have been released approximately every four years, 1998<ref>{{cite web |url=http://www.nodc.noaa.gov/OC5/indpub.html#World%20Ocean%20Atlas%201998 |title=World Ocean Atlas 1998 series |publisher=[[National Oceanographic Data Center]]}}</ref>, 2001<ref>{{cite web |url=http://www.nodc.noaa.gov/OC5/WOA01/pr_woa01.html |title=World Ocean Atlas 2001 |publisher=[[National Oceanographic Data Center]]}}</ref>, and 2005<ref>{{cite web |url=http://www.nodc.noaa.gov/OC5/WOA05/pr_woa05.html |title=World Ocean Atlas 2005 |publisher=[[National Oceanographic Data Center]]}}</ref>. The most recent World Ocean Database series, WOD09, was released in September 2009<ref>{{cite web |url=http://www.nodc.noaa.gov/OC5/WOA09/pr_woa09.html |title=World Ocean Atlas 2009 |publisher=[[National Oceanographic Data Center]]}}</ref>. The WOD09 has more than 9 million temperature profiles and 3.6 million salinity profiles. The table shows a comparison of the number of stations by instrument type in WOD09 with previous NODC/WDC global ocean databases.

The data in the World Ocean Database are made available through the on lineonline search and retrieval system known as the WOD''select''. Another project using the World Ocean Database variables is theThe [[World Ocean Atlas]] (WOA''select'') series is a set of gridded (1° grid), climatological, objectively analyzed fields of the variables in the World Ocean Database. The WOA''select'' is a selection tool by which the user can designate a geographic area, depth, and oceanographic variable to view climatological means or related statistics for a given variable at the requested depth for the requested geographic area. The World Ocean Atlas series is a set of gridded (1° grid), climatological, objectively analyzed fields of the variables in the World Ocean Database.
